- 1What is the pH scale and what is its range?The pH scale is a measurement of the acidity or alkalinity of solutions
The pH scale is from 1-14 - 2What are the 4 bases that neutralize an acidMetal Oxide
Metal
Metal Carbonates
Alkali - 3What is neutralization?a Chemical reaction where the pH solution moves towards 7
- 4What is a spectator ionThey are ions that appear on both sides of an equation and which are not changed in the reaction
- 5What is an acidic solutiona solution which as more hydrogen + ions than OH- ions. They also have a pH level of 1-6
- 6What is an alkaline solutiona solution which as more hydroxide - ions than H+ ions. They also have a pH level of 8-14
- 7What pH is pure water7
- 8True or false: Lime water has a pH of 16False the pH scale only goes form 1-14
- 9A Metal oxide reacts with an alkali to giveSalt + Water
- 10What would Hydrochloric acid and Potassium oxide react to give?Water and Potassium Chloride
- 11What does sodium carbonate and nitric acid react to giveWater + CO2 and sodium nitrate
